International c orrelation s tructure Security returns are much less correlated across countries than within a country. This is true because economic, political, institutional, and even psychological factors affecting security returns tend to vary across countries, resulting in low correlations among international securities.Business cycles are often asynchronous across countries.

The realized dollar return for a U.S. resident investing in a foreign market is given by R i $ = (1 + Ri)(1 + ei) – 1 = Ri + e i + R i e i where Ri is the local currency return in the i th market. ei is the rate of change in the exchange rate between the local currency and the dollar. Effects of changes in the exchange rate

Example Suppose that a U.S. resident just sold shares in a British firm that had a 15% (local) return in pounds during a period when £ depreciated 5%, his $ return is 9.25%: Ri$ = (1 + .15)(1 – 0.05) – 1 = 0.925 = . 15 + –.05 + .15×(–.05) = 0.925

Variance decomposition Reall R i $ = (1 + Ri)(1 + ei ) – 1 = R i + e i + Ri ei The risk for a U.S. resident investing in a foreign market will depend not only on the risk in the foreign market but also on the risk in the exchange rate between the U.S. dollar and the foreign currency. Var(Ri$) = Var(Ri) + Var(ei) + 2Cov(Ri,ei) + Var The Var term represents the contribution of the cross-product term, Riei, to the risk of foreign investment.

Effects of changes in the exchange r ate Var ( Ri$) = Var(R i ) + Var ( e i ) + 2Cov( Ri ,ei) + Var This equation demonstrates that exchange rate fluctuations contribute to the risk of foreign investment through three channels:Its own volatility, Var(ei ).Its covariance with the local market returns Cov(Ri,ei).The contribution of the cross-product term, Var.

Variance decomposition, 1990-2012

Implication for equity investing Based on Var ( Ri), $ return is largely driven by local return.Changes in exchange rate plays a secondary role, as evident by the size of Var(ei).

Implication for bond investing Based on VAR( e i ), there is substantial exchange rate risk in foreign bond investment. This suggests that investors may be able to increase their gains if they can diversify exchange rate risk away internationally.This also suggests that investors may be able to control this risk with currency forward contracts or swaps.

Home bias in portfolio h oldings As previously shown, investors can potentially benefit a great deal from international diversification. The actual portfolios that investors hold, however, are quite different from those predicted by the theory of international portfolio investment. Home bias refers to the extent to which portfolio investments are concentrated in domestic assets.

Home bias in equity p ortfolios Country Share in World Market Value Proportion of Domestic Equities in Portfolio Australia 1.70 78.91 Brazil 0.71 100.00 Canada 2.67 28.67 Germany 3.21 29.35 Japan 9.29 98.50 Sweden 1.0048.56United Kingdom 7.6442.95United States 44.8686.88

Three conventional explanations: Domestic equities may provide a superior inflation hedge. Home bias may reflect institutional and legal restrictions on foreign investment. Extra taxes and transactions/information costs for foreign securities may give rise to home bias. Why home bias?

Why home b ias? Bailey et al. (2004) found that wealthier , more experienced, sophisticated investors are more likely to invest in foreign securities. Chan et al. (2005) found that when a country is remote and has an uncommon language, foreign investors tend to stay away.

Structuring international investing Most international institutional investors use the top-down approach because they value the importance of asset allocation. The process is structured along the lines of the national market influences (national market factors are the major factors). The entire structure has 4 stages.

Stage 1 Market analysis and security analysis International research department Generate forecasts on exchange rates, interest rates, commodity prices, and national stock market returns.Provide expected returns and risk sensitivities measured in $, along with recommendations, on individual securities.Maintain an active list of individual securities in each asset class. Provide properly undated expected returns and expected covariance matrix measured in $ (this is no easy task).

Stage 2 Asset allocation Strategist or investment policy committeeComputer-based (mean-variance) optimization models or subjective judgmentOnce asset allocation decision is made, the asset allocation mixture should appear on portfolio managers’ terminals.

Stage 3 Portfolio construction Portfolio manager(s )Inputs: (1) the asset allocation mixture, and (2) an active list of individual securities in each asset class.Form and/or maintain a portfolio that complies with the asset allocation mixture.

Stage 4 Internal monitoring Daily internal accounting systemReview committee (Fidelity)Quarterly or annually performance evaluation

Country f unds Recently, country funds have emerged as one of the most popular means of international investment. A country fund invests exclusively in the stocks of a single county. This allows investors to: Speculate in a single foreign market with minimum cost. Construct their own personal international portfolios. Diversify into emerging markets that are otherwise practically inaccessible.

American d epository receipts (ADRs) Foreign stocks often trade on U.S. exchanges as ADRs. An ADR is a receipt that represents the number of foreign shares that are deposited at a U.S. bank. The bank serves as a transfer agent for the ADRs. Examples: BP, Barclays Bank, Taiwan Semiconductor Manufacturing, LG Display, etc.

ADRs There are many advantages to trading ADRs as opposed to direct investment in the company’s shares: ADRs are denominated in U.S. dollars, trade on U.S. exchanges, and can be bought through any broker. Dividends are paid in U.S. dollars. Most underlying stocks are bearer securities and the ADRs are registered (no voting rights).Adding ADRs to domestic portfolios has a substantial risk reduction benefit.

WEBS In April 1996, the American Stock Exchange (AMEX) introduced a class of securities called World Equity Benchmark Shares (WEBS), designed and managed by Barclays Global Investors. In essence, WEBS are exchange-traded funds (ETFs) that are designed to closely track foreign stock market indexes. Currently, there are 23 WEBS tracking the Morgan Stanley Capital International (MSCI) indexes for the following individual countries: Australia, Austria, Belgium, Brazil, Canada, Chile, China, France, Germany, Hong Kong, Italy, Japan, Korea, Malaysia, Mexico, the Netherlands, Singapore, South Africa, Spain, Sweden, Switzerland, Taiwan, and the United Kingdom.

ETFs Using ETFs like WEBS and spiders, investors can trade a whole stock market index as if it were a single stock. Being open-end funds, WEBS trade at prices that are very close to their net asset values. In addition to single country index funds, investors can achieve global diversification instantaneously just by holding shares of the S&P Global 100 Index Fund that is also trading on the AMEX with other WEBS.

International money m arket Eurocurrency is a time deposit in an international bank located in a country different than the country that issued the currency. For example, Eurodollars are U.S. dollar-denominated time deposits in banks located abroad. Euroyen are yen-denominated time deposits in banks located outside of Japan.The foreign bank doesn’t have to be located in Europe.

Eurocurrency market Most Eurocurrency transactions are interbank transactions in the amount of $1 million and up. Common reference rates of $ include: LIBOR (London Interbank Offered Rate) PIBOR (Paris Interbank Offered Rate) SIBOR (Singapore Interbank Offered Rate)A new reference rate for the new euro currency:EURIBOR (the rate at which interbank time deposits of € are offered by one prime bank to another)

Eurocredits Eurocredits are short- to medium-term loans of Eurocurrency. The loans are denominated in currencies other than the home currency of the Eurobank. Often the loans are too large for one bank to underwrite; a number of banks form a syndicate to share the risk of the loan. Eurocredits feature an adjustable rate. On Eurocredits originating in London the base rate is LIBOR.

Euronotes Euronotes are short-term notes underwritten by a group of international investment banks or international commercial banks. They are sold at a discount from face value and pay back the full face value at maturity. Maturity is typically three to six months.

Eurocommercial paper Unsecured short-term promissory notes issued by corporations and banks. Placed directly with the public through a dealer; typically, not underwritten by a bank. Maturities typically range from one month to six months.Eurocommercial paper, while typically U.S. dollar denominated, is often of lower quality than U.S. commercial paper—as a result yields are higher.

Foreign bond vs. Eurobond Foreign bond: offered by a foreign borrower to the investors in a national capital market and denominated in that nation’s currency. Example: A German MNC issues $-denominated bonds to U.S. investors. E urobond : a bond issue denominated in a particular currency (usually $, ¥, €) but sold to investors in national capital markets other than the issuing country. Example: a Singapore borrower issues $-denominated bonds to investors in Japan.The eurobond segment accounts for about 80% of international bond market.

Bearer bonds vs. registered b onds Bearer bonds are bonds with no registered owner. As such they offer anonymity, but they also offer the same risk of loss as currency. Eurobonds are usually bearer bonds. Registered bonds are bonds where the owner’s name is registered with the issuer. U.S. security laws require Yankee bonds and U.S. corporate bonds sold to U.S. citizens to be registered.A Yankee bond is a bond issued by a foreign entity, but is issued and traded in the United States and denominated in U.S. dollars; a Yankee bond is a type of foreign bond.

National security r egistrations Yankee bonds must meet the requirements of the SEC, just like U.S. domestic bonds. Many borrowers find this level of regulation burdensome and prefer to raise U.S. dollars in the Eurobond market. Eurobonds sold in the primary market in the United States may not be sold to U.S. citizens. Of course, a U.S. citizen could buy a Eurobond on the secondary market.

Global bonds A global bond is a very large international bond offering by a single borrower that is simultaneously sold in North America, Europe, and Asia. Global bond issues were first offered in 1989. Global bonds denominated in U.S. dollars and issued by U.S. corporations trade as Eurobonds overseas and domestic bonds in the U.S.

Dual-currency b onds A straight fixed-rate bond with interest paid in one currency and principal in another currency. Japanese firms have been big issuers, with coupons in yen and principal in dollars. Can be a good option for an MNC financing a foreign subsidiary. 0 1 3 4 N N – 1 ¥ ¥ ¥ $ ¥

Sovereign bond Sovereign b ond: a debt security issued by a national government. Sovereign bonds can be denominated in a foreign currency or the government’s home currency. A sovereign government controls its own affairs and thus cannot be obliged to pay back its debt (unless the lending countries are willing to use the force).There exits no international court to enforce the payment either. So there is no international version of Chapter 11.When a government defaults, it will be excluded from further credit. So a default is usually the last resort.

Argentina default + bondholders’ holdout “Argentina defaulted on a record $95 billion in 2001, disrupting international credit markets and setting up bitter fights with its disappointed creditors. About 92 percent of bondholders agreed to exchange their debt for new bonds, at a discount of about 70 percent, in restructurings in 2005 and 2010 .” “Argentina can go ahead with a planned $15 billion bond sale to pay off holdout creditors from a 2001 default, ending more than a decade of litigation over repayment of the debt that kept South America’s second-biggest economy out of international credit markets.”Bloomberg, 04/13/2016

Credit r atings Fitch, Moody’s, and Standard & Poor’s sell credit rating analysis. Focus on default risk, not exchange rate risk. Assessing sovereign debt focuses on political risk and economic risk. “Ratings company cuts Brazil's grade by two steps to Ba2 (junk),” Bloomberg, 02/24/2016.Brazil 10-year government note had a yield of about 6.7% vs. U.S. 10-year T-note yield of <2%.

Eurobond market s tructure Primary market Very similar to U.S. underwriting: intermediated by an underwriting syndicate of investment banks. Secondary market OTC market centered in London. Comprised of market makers as well as brokers.

Eurobond: p rimary m arket A borrower desiring to raise funds by issuing Eurobonds to the investing public will contact an investment banker and ask it to serve as the lead manager of an underwriting syndicate that will bring the bonds to market. The underwriting syndicate is a group of investment banks, merchant banks, and the merchant banking arms of commercial banks that specialize in some phase of a public issuance. The lead manager will sometimes invite co-managers to form a managing group to help negotiate terms with the borrower, ascertain market conditions, and manage the issuance.

Eurobond: p rimary m arket The managing group, along with other banks, will serve as underwriters for the issue. They will commit their own capital to buy the issue from the borrower at a discount from the issue price. The discount, or underwriting spread, was typically in the 2 percent range; it is about 1% today. Meanwhile, the spread averages about 1 percent for domestic issues. Most of the underwriters, along with other banks, will be part of a selling group that sells the bonds to the investing public.

Eurobond: s econdary m arket Eurobonds initially purchased in the primary market from a member of the selling group may be resold prior to their maturities to other investors in the secondary market. The secondary market for Eurobonds is an over-the-counter market with principal trading in London. However, important trading is also done in other major European money centers, such as Zurich, Luxembourg, Frankfurt, and Amsterdam.

€-denominated eurobond “FedEx , the US-based courier service, and Carmila , a French real estate company, have mandated banks to begin a set of investor meetings to launch euro-denominated bonds .”“Companies have been rushing to take advantage of the low yields on offer for euro-denominated debt in the aftermath of the European Central Bank’s announcement that it will begin buying corporate debt.”“Much of the euro debt sold by overseas companies is issued to fund their European activities, potentially providing the boost to the eurozone economy that the ECB wishes to see, while others will swap their debt back into their home currency.” Source: Financial Times, 03/17/2016.

International bond m arket i ndices There are several international bond market indices. JP Morgan and CompanyDomestic bond indices. International government bond index for 18 countries.Widely referenced and often used as a benchmark. Appears daily in The Wall Street Journal.

Equity market: developed c ountries At year-end 2012, total market capitalization of the world’s equity markets stood at $53,164 billion. Of this amount, 75 percent is accounted for by market capitalization of major equity markets from 31 developed countries.

Emerging markets Standard & Poor’s Emerging Markets Database classifies a stock market as “emerging” if it meets at least one of two general criteria: It is located in a low- or middle-income economy as defined by the World Bank. Its investable market capitalization is low relative to its most recent GNI (gross national income) figures.

Measures of liquidity One measure of liquidity for a stock market is the turnover ratio:   The higher the ratio, the more liquid the market. In 2012, the turnover ratio varied from a low of 2 (for Bahrain) to a high of 164 (for China). For the majority of emerging markets, there is poor liquidity.

Measures of market c oncentration Emerging markets tend to be much more concentrated than our markets. Concentrated in relatively few companies. That is, a few issues account for a much larger percentage of the overall market capitalization in emerging markets than in the equity markets of the developed world. The number of equity investment opportunities in emerging stock markets in developing countries has not been improving in recent years.

Cross-listing of shares Cross-listing refers to a firm having its equity shares listed on one or more foreign exchanges. The number of firms doing this has exploded in recent years.

Advantages of cross-listing It expands the investor base for a firm. Very important advantage for firms from emerging market countries with limited capital markets. Establishes name recognition for the firm in new capital markets, paving the way for new issues. May offer marketing advantages. Cross-listing into developed markets with strict securities regulations and information discloser may signal investors that improved corporate governance is forthcoming.May mitigate possibility of hostile takeovers.

Yankee stock o fferings The direct sale of new equity capital to U.S. public investors by foreign firms. Privatization in South America and Eastern Europe. Equity sales by Mexican firms trying to “cash in” following implementation of NAFTA.

Global registered s hares The merger of Daimler Benz AG and Chrysler Corporation in November 1998 created DaimlerChrysler AG, a German firm. The merger simultaneously created a new type of equity share, called Global Registered Shares (GRSs). GRSs are traded globally, unlike ADRs, which are traded on foreign markets. The company was renamed Daimler AG in October 2007 when it spun off Chrysler. The primary exchanges for Daimler GRSs are the Frankfurt Stock Exchange and the NYSE; however, they are traded on a total of 20 exchanges worldwide. The shares are fully fungible—a GRS purchased on one exchange can be sold on another. They trade in both U.S. dollars and euro.
